Currently lowers the following instructions: DST, XPD, SCS, LRP, FRC, POW, LIT, EXP, LOG, DP4, DP3, DPH, DP2 translating these into equivalent simpler TGSI instructions. This probably should be moved to util so other drivers can use it, but just adding under freedreno for now so that I can clear out a lot of the lowering code in a3xx compiler before beginning to add new compiler.
